Analytical Chemistry of Niobium and Tantalum details the methods in understanding the chemistry of niobium and tantalum, which includes separation, identification, and quantification. The text first discusses the general topics about niobium and tantalum, such as history, metallurgical properties, and applications. Next, the selection covers the properties of niobium and tantalum and their compounds. The subsequent chapters tackle the various analytical chemistry processes that can be applied to niobium and tantalum, such as spectrographic determination; titrimetric methods; and colorimetric determinations. The book will be of great use to chemists, chemical engineers, and metallurgists.
In Chemistry of Tantalum and Niobium Fluoride Compounds, the author draws on thirty years' experience to produce the first ever monograph to systemize and summarize the data available on tantalum and niobium fluoride compounds.
To determine niobium and tantalum in rocks and minerals , photometric and gravimetric methods are mainly employed . ... Structurally , the analytical scheme of a complete chemical analysis depends on the combination of chemical elements ...
The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved.
